Re: [Phys-l] Greenhouse effect / 2nd law

Addendum to my previous note:

Think about the meaning and etymology of the word itself:
Equilibrium.  It speaks of equality.

Mechanical equilibrium doesn't mean zero force;  it means
*equal* forces.

Thermal equilibrium doesn't mean no energy flow;  it means
*equal* energy flow in and out.

Chemical equilibrium doesn't mean no reaction rate;  it means
*equal* reaction rates to the left and to the right.
